14 November 2012 -- Source BioScience plc (LSE: SBS), the international diagnostics and genetic analysis business serving the healthcare and research markets today publishes its Interim Management Statement for the period from 1 July 2012 to 14 November 2012.

Unless otherwise stated, the financial information referenced below refers to the three months ended 30 September 2012, and the corresponding period last year, this being the latest practicable date to which financial information has been prepared.

Overall business performance

The third quarter of 2012 has been another period of sustained growth and development for Source BioScience with increased revenue in both the LifeSciences and Healthcare divisions, compared with the same period last year.

This performance has been underpinned by growth in the Cytology business, driven by the adoption of automated imaging for cervical cancer screening, coupled with increasing market share for DNA sequencing in the UK.

The Group remains in a robust financial position with £2.0 million cash at the end of September 2012 (30 June 2012: £1.8 million).

Overall performance for the year to date is in line with management’s expectations, representing a continuation of the strong business performance achieved last year. We expect full year profits to be in line with market expectations.

LifeSciences division

The Overnight Service for DNA sequencing has enabled the Group to further increase its share of the UK market. Sequencing volumes during Q3 were 27% greater than the same period last year and 46% up on a year to date basis. This enhanced service has also enabled the Group to win sequencing tenders from the Universities of Warwick and Newcastle.

In July we announced an extended next generation sequencing service using the new Illumina MiSeq™ platform. This platform addresses the “middle ground” between the Group’s existing sequencing technologies and has already attracted customers from both the life science research and healthcare communities.

GenomeCube®, our proprietary search engine and bioinformatics tool for our clone and antibody portfolio, has enabled the appointment of additional distributors, extending the global reach of our products business. In August we announced the appointment of a third distributor in the important South East Asia market, Benebiosis of South Korea, and in the period we appointed a fourth distributor in the region, Michrom of Malaysia. During the period we further enhanced our network in Europe with additional distributors appointed in Turkey, Italy and Poland.

Healthcare division

Demand for our liquid based cytology (‘LBC’) service, which supports 50% of the Cervical Cancer Screening Programme for England and Wales, continues to be strong. The roll out of the BD FocalPoint™ automated imaging platform for cervical cancer screening has driven growth in the Cytology business. In the short term, we expect a number of additional NHS Trusts to adopt this imaging technology.

Molecular diagnostic testing continues to gain clinical relevance and importance in the NHS, especially gene-based companion diagnostic testing. Companion diagnostic testing provides information about how a patient might respond to a particular drug therapy. One of the most widely utilised tests is the K-RAS gene test for colorectal cancer and demand in the period was up more than 70% compared with the same period last year.

Source BioScience is one of only a few accredited laboratories in Europe with the capability to deliver this type of complex diagnostic testing and the growing demand strengthens the Group’s commercial advantage.

To conclude, the Group has made good progress in the period and we expect full year profits to be in line with market expectations.
